6. Analyze a Transient Thermoreflectance Image in SanjANALYZER

SanjANALYZER opens .fdi (Low Frequency) or .tti (Transient) data files. Load a thermal image by double-clicking the file of interest in the file selection control; the CCD and thermal images then appear in the display windows.

Worked example — image series analysis:

1. Select the first image of the transient series.
2. Enter the "number of images in the series" (51 in the example).
3. Select an ROI box on the area of interest (on top of the 5 µm Gold heater in the source example).
4. Select "Process Series."

The software steps through the image series and plots the data in the "ROI Mean Series" graph, lower left. Right-click the y-axis to auto-scale the graph.

Reference: Under the Cross-Section tab, select the correct "Objective" used during imaging to get the correct pixel-to-distance scale before saving a cross-section (ASCII, tab-delimited).
